Was watching this movie with a friend of mine, we are both huge in to movies over 30 years. All we were talking about was the performance by Alva. SIMPLY STUNNING! I was convinced that Anna was a real autistic girl. I hope this movie will get the recognition it deserves. As for the story, it's not your straight forward everyday thriller/horror. There is room for your imagination to fill in the gaps, which is an oddity nowadays.
